Abstract

A gas relay for optical fiber trip of an intelligent substation mainly comprises a casing and an air vent valve. Light gas and weighted gas are filled in the casing, the light gas comprises a light gas floater arranged at the bottom, a light gas connecting rod is connected on the light gas floater, a light gas light shelter plate is connected on the upper portion of the light gas connecting rod, and a light gas light transceiver is configured at one end of the light gas light shelter plate and transmits alarm signals to a substation monitoring system through an optical fiber. The weighted gas comprises a weighted gas floater at the bottom, a weighted gas connecting rod is connected on the weighted gas floater, an oil flow retaining plate is arranged at the lower end of the weighted gas connecting rod, a weighted gas light shelter plate is connected at the upper end of the weighted gas connecting rod, and a weighted gas light transceiver is configured at one end of the weighted gas light shelter plate and can transmit alarm signals to the substation monitoring system through the optical fiber. Since the internal electromagnetic environment of the substation is complicated, the optical fiber as medium has high anti-interference capability and good electromagnetic compatibility and the like as compared with dielectric medium, and reliability of non-electric quantity protection of a transformer can be further improved.

Description

technical field [0001] The invention relates to a gas relay for transformer gas protection, in particular to a gas relay for optical fiber tripping in an intelligent substation, and belongs to the field of relay protection. Background technique [0002] The smart substation adopts advanced, reliable, integrated, low-carbon, and environmentally friendly smart equipment. With the basic requirements of digitalization of the whole station information, networking of the communication platform, and standardization of information sharing, it automatically completes information collection, measurement, control, protection, measurement, and monitoring. and other basic functions, and can support power grid real-time automatic control, intelligent adjustment, online analysis and decision-making, collaborative interaction and other advanced functions of the substation as needed. [0003] As a node of the power network, the smart substation is connected to the line and transmits electric...
